Description
(1) technical field:
The present invention relates to a kind of air cleaner, especially a kind of circulating type air cleaner and method of work thereof automatically.
(2) background technology:
Auto reeling type air cleaner result since 1978 promote at home shows: have that serviceability is stable, filter effect good, working service facilitate one-time investment few, filter the features such as filter material can also be washed Reusability, and operating cost is low.Moving curtain filter, except the GB such as TL-3, YG4 product, has successively added again some products such as NZJ type reversible coiling air cleaner, YG4-II herringbone coiling air cleaner recently on market.Although these products are through development and progress for many years, but also exist many problems and drawback, such as: 1. filter the initial resistance of filter material when bringing into use and arrive whole resistance after using a period of time, when high-drag to having certain influence in fan pressure, air quantity and power consumption; 2. in the time changing filtration filter material, no matter be reversible feeding system, still there is the air cleaner of stock shelf system all take a lot of work and require great effort; Although 3. above-mentioned filtration filter material is all that can wash with water can the clean material of blowback, but because these filter materials are all the materials that dust containing capacity is larger, dust enters filter material inside completely and is not easy to clean up very much, so most user is disposable; Change so frequently the cost that filter material has increased operation, further cause again the secondary pollution of environment.
(3) summary of the invention:
The object of the present invention is to provide a kind of circulating type air cleaner and method of work thereof automatically, it can solve the deficiencies in the prior art, by cleaning device, filter material is carried out to periodic cleaning, and circulating type air cleaner can recycle, energy-conserving and environment-protective.
Technical scheme of the present invention: circulating type air cleaner automatically, is characterized in that it comprises screen pack, control of dust hopper, directive wheel, dust removal brush, deep bead, roller bearing, dust removal brush drive motors reductor and screen pack drive motors reductor; Described screen pack is closed annular, is wound on roller bearing and directive wheel; Described roller bearing is connected with directive wheel; In described directive wheel, comprise driving wheel, driving wheel is connected with screen pack drive motors reductor; Described dust removal brush contacts with screen pack, and is connected with dust removal brush drive motors reductor; Described dust removal brush below arranges control of dust hopper; The air outlet side of described circular filter net is in deep bead.
Described driving wheel is by chain and screen pack drive motors reductor.
Described screen pack is pressed on dust removal brush by tensioner roller bearing.
Described screen pack forms by filtering the annular guipure of filter material and stainless steel; Described filtration filter material is fixed on stainless steel annular guipure surface.
